S 10 Rear axle width

Who knows the total axle width of S 10 rear end. Are they all the same? What size brake drum do they have?

4x4 is wider than the 2x4. if i remember right 2wd is around 55", BUT DON'T HOLD ME TO THAT

 

The 2 wd 92 one I bought was 55 from face of drum to face of drum.

 

This is good news guys. I need a narrow 5x4 3/4" unit for a 51 Ford. The stock axle is 57" so maybe I'm on the right track.

I believe the rear from a late '70s to late '80s g-body is '58 inches, which might make it a good option. I'm pretty sure the 4x4 S-10 is wider than the 2-wheel-drive, but don't have dimensions.
